Here at the Model Roller Coaster HQ Vintage Model Steam Locomotive Works we are very particular when it comes to adding sound to our awesome vintage steam locos. After all, our clients deserve the finest vintage steam locomotives with only the very best sound quality from only the very best manufacturers. That's why we only offer sale and installation of TCS WOWSound® and Soundtraxx Tsunami® 16 Bit sound decoders as an option for many of our fully restored vintage locos. Enter the NEW TSU-750 Micro-Tsunami® Digital Sound Decoder™ from Soundtraxx. With its diminutive size, this full-featured powerhouse now makes possible the addition of state-of-the-art 16 bit sound to many locos where previous larger 16 bit decoders simply wouldn't fit. Wait, we're not done. In locos that DO have adequate installation space, using a smaller decoder also allows extra room for larger speakers and larger speaker enclosures.

Voilà, bigger and better sound and we do like "better". Not to be outdone, TCS will soon debut their own "micro" 16 bit decoder the WOWSound 1539. Stay tuned.

TSU-750 Micro-Tsunami® Digital Sound Decoder™

The incredibly small Micro-Tsunami provides waves of pure 16-bit digital sound that will delight your senses; with effects so amazing you won't believe your ears. This little sound system is so complete, yet sacrifices nothing!

Micro-Tsunami's sound features are matched only by its superior motor control and brilliant lighting effects, making it unsurpassed in its technological capabilities. A 32-bit digital signal processor provides the necessary horsepower Tsunami needs to support more functions, sound effects, advanced motor control and yet, measures just 25.5mm x 13mm x 5.5mm.

Small Size, Big Features

Micro-Tsunami steam decoders can produce over 22 sound effects, including the bell, whistle, airpump, dynamo, snifter valve, injectors, firebox blower, side rod clank, brake squeal, exhaust chuff and more. Pull up to the water tank and activate the Water Stop effect -- a steam engine won't get far without water! Fireman Fred has a few new things up his sleeve as well, as he works to keep the locomotive in prime operating condition. Use the Auto-Exhaust™ feature to adjust the exhaust cadence to correspond to a 2-cylinder, articulated or geared locomotive or use a cam if you prefer.

The diesel version can produce over 14 sound effects, including the engine startup and shutdown, engine prime mover through all eight notches, bell, airhorn, air compressor, dynamic brakes, radiator fans, brake squeal, and more.

Micro-Tsunami goes several steps beyond ordinary sound generators. It is so powerful that it comes with four special effects processors -- the Equalizer, Sound Mixer, Dynamic Digital Exhaust and Reverb. It's like having a complete sound studio at your fingertips!

Brilliant Lighting Effects

Micro-Tsunami includes two outputs for our Hyperlight™ lighting effects to reproduce the most popular warning beacons.

Advanced Motor Control

We designed Hyperdrive™ technology into the Micro-Tsunami, resulting in smooth and precise locomotive operation. Hyperdrive includes many features, such as high-resolution speed steps, high-frequency PWM drive, and torque control, all designed to improve the running characteristics of your locomotive.

Prototypical Operation

With the press of a key on your DCC controller, you can blow horns and whistles, ring the bell, and watch the headlight sputter to life as the power builds up. The more functions your controller has, the more fun you'll have!
